Chapter 6: Obtaining Service

1. Use the Troubleshooting section to eliminate obvious causes.
2. Verify there are no tripped circuit breakers and that the batteries are good.
A tripped circuit breaker and defective batteries are the most common iss-
ues.
3. Call your dealer for assistance. If you cannot reach your dealer, or if they
cannot resolve the issue call or fax the Technical Support department at the
following numbers; Voice phone (972) 446-7363, FAX line (972) 446-9011
or visit our Web site at www.minutemanups.com the "Discussion Board".

or error codes displayed.
f)
A description of the protected equipment including model numbers, if
possible.

A technician will ask you for the above information and if possible,
help solve the issue over the phone. In the event that the unit requires
factory service, the Technical Support Representative will issue you a
Return Material Authorization Number (RMA #).
NOTE:
We must
have the model number and the serial number of the product to
issue an RMA #.
h)
If the unit is under warranty, the repairs will be done at no charge. If
the unit is not under warranty there will be a charge for the repair.
4. Pack the unit in its original packaging. If the original packaging is no lon-
ger available, ask the Technical Support Representative about obtaining a
new set. It is important to pack the unit properly in order to avoid damage
in transit. Never use Styrofoam beads for a packing material.
a)
Include a letter with your name, address, day time phone number,
RMA number, a copy of your original sales receipt, and a brief desc-
ription of the problem.
5. Mark the RMA # on the outside of all packages. The factory cannot accept
any package without the RMA # marked on the outside of the package.
